LR023964 Air Suspension Compressor Pump (Hita-chi System) Replacement for 2006-2013 Range Rover Sport LR044360 2005-2009 LR3,2010-2013 LR4 6 Pins

I have a 2006 Range Rover Land Rover Sport HSE, 4.4L V8.When the ambient temperature was over 100F, the air compressor would stop working and faults were triggered. The faults would alternate between yellow and red. The compressor couldn't keep up with the demand, overheated and then shut off, causing lots of issues while driving.The replacement took about 20 minutes. Tools needed are a ratchet, long extension, and 10mm socket.The air lines on the old one were a bit difficult to remove because they are 18 years old. Eventually they popped off.The new compressor fit perfectly, and everything lined up. It has been two days since I replaced the compressor and no more faults. Ride heights adjust from off-road to access quickly and with no problems.The old one had 140,000 miles on it. I hope this one will last just as long.

The first pump arrived and the airline fittings popped right out was not usable. They did an exchange and the second pump came I installed and it seemed to be a bit weak and noisy, but it was working fast-forward 4 1/2 months just like every other review says the pump stopped working it is overheating and barely putting out air, I contacted the company about the warranty. They want me to take the pump out and take pictures of the pump and the numbers and pictures of the fault code on the vehicle. This is not a very convenient solution for a warranty after not even six months. I am not going to remove the pump until I rebuild my stock pump as in the pump does slowly work to add air but overheats after about two minutes of running. I even tried removing the airline that feeds the tank and the pump barely pushes any air out. This was definitely an internal failure, like everyone else says.

Had “air pressure rising slowly” code on my 2009 LR3, replaced stock Hitwchi compressor with this one. Was a little apprehensive of the low price at first, but the unit looks exactly like the unit bein replaced, except it doesn’t have a LandRovee logo. Air pressure rises fast, noise level is the same as the stock compressor, and the air suspension code I had before has not come up so far (our about 400miles on the car since the replacement). Have nothing to complain about so far, and he price is amazing. Will try to remember to update this review after a year.

8/7/2019: Purchased this compressor in March 2019 and after only 4 months of use it is already a problem. Started getting louder in the past week and yesterday it sounded like a box of marbles and faulted for low output. Had my local LR shop reset the system a few times with no change. Keeps faulting. Compressor shakes heavy and sounds awful. The shop said its garbage and needs a new one installed. Cannot drive my truck now. Sent an email to the seller asking for a warranty replacement or refund. Will update this review with results.8/11/2019 sent another email asking for a replacement or refund.8/16/19 Have yet to hear back from the seller/manufacture about my issue. Sent the 3rd email today asking for a replacement or refund. Gave them scan info showing low output fault.10/9/19 still no help or response from the seller about a warranty replacement..VIN: SALAD25446A39XXXXL319 - LR3 2006Vehicle scanned on 16-08-2019 08:49Using IIDTool BT V3.0 B2481Suspension•C1A20-64 (2E) Pressure increases too slow when filling reservoir - Algorithm based failure - signal plausibility failure( on 07-08-2019 14:11:37 at 149649 mi )

I was sceptical but decided to try this pump. I installed it after getting the fault message and yellow light from factory pump. it has been working fine for 3 months now and I have a slow leak in one of the valve blocks, takes a week or so to completely air down. This pump has been able to keep the suspension working great with no codes and it doesn't run excessively to air up suspension when vehicle is started. I have purchased a rebuild kit for my factory pump so I have a backup. I recommend doing this as well for piece of mind.

The compressor fit perfectly in the place of the old one. You can place them side by side and they are a perfect match. The bracket is not included but not needed since the original one can be re used. This is the "Hitachi" brand unit.It worked great, fired up immediately. Fixed my issue. Would order again from this supplier.Update 02/03/2020-> the pump has failed. Only pumping 50 psi instead of the 200 psi it should be producing. Not a quality product as reported earlier.

Installed it, ran OK for a short bit. Started getting fault codes again after a week. Got worse and worse and now it doesn't work. Pressure test 0 PSI. This supplier says it has a 2 year warranty, but after reading other reviews I have a feeling getting them to replace it will be difficult. I hope they prove me wrong. Asking them to replace mid April 2019, lets see what happens. Will update review if replaced or if left hanging.Update 4/19/19:the company replied within hours asking for more details, photos, video and serial number. I just sent them more details and a photo of the serial number. Will update as this progresses.Update 4/24/19After a few emails back and forth, the company has been very responsive. At their suggestion I ordered another pump from them to speed up the process after they would refund the new one to cover the warranty. I have the new pump, They design is better, the build is better, quieter, more powerful. So far so good. So from one star to 4 stars. If anything changes I will update here, but so far I am impressed with the company.

Excellent 👍👍
